Add ERC-8041: Fixed-Supply Agent NFT Collections

Summary

This PR introduces ERC-8041, a standard for creating fixed-supply collections of ERC-8004 Agent NFTs with mint number tracking.

Motivation

While ERC-8004 provides unlimited minting for AI Agent identities, many use cases require limited collections (e.g., "Genesis 100", "Season 1"). ERC-8041 addresses this need by defining a standard interface for fixed-supply collections.

Key Features

• Fixed Supply Limits: Define maximum number of agents per collection
• Mint Number Tracking: Permanent tracking of each agent's position (e.g., "5 of 1000")
• Onchain Collection Metadata: Links agents to their collections via the "agent-collection" metadata key
• Time-Gated Releases: Collections can activate at specific block numbers

Technical Details

Core interface includes:

• getAgentMintNumber(uint256 agentId) - Returns agent's position in collection
• getCollectionDetails() - Returns supply info and collection status
• Events: CollectionCreated, AgentMinted

Compatibility

• Requires: ERC-8004
• Compatible with: ERC-721

Note on Direction Change

This ERC represents a strategic shift in approach. Originally, ERC-8041 was planned as a standalone contract-level metadata standard. We've pivoted to instead leverage the existing Onchain Metadata functionality of ERC-8004, focusing on a specific application (fixed-supply agent collections) rather than the underlying metadata infrastructure.

This decision prioritizes implementation speed by repurposing the existing ERC number rather than submitting a new proposal and going through the numbering process again. This allows immediate adoption of onchain metadata capabilities using ERC-8004 registries with the agent-collection metadata key. A future ERC will standardize the Onchain Metadata interface itself.
